Aug 05, 2026 CVE-2026-16736
User Registration permits account creation while registration is disabled
User Registration & Membership before 5.2.6 processes public registration-form submissions without enforcing WordPress's registration-disabled setting. An unauthenticated visitor can therefore create a new account despite the administrator having closed registration. This unscored record received deeper review because it gives unauthenticated callers an account-creation primitive that may become more serious when forms assign elevated or application-specific roles. The CNA does not disclose the form route, action or parameters.
